Do all browsers have local storage?

Question

I wanted to know if it's necessary to do a check if local storage is present or not when I try to use it.

Ie, I have this as a check:

  if (global.localStorage) {
    global.localStorage.setItem('layout', JSON.stringify({
      [key]: value
    }));
  }

Or can I use localStorage without this check?
